Hey guys !
Thanks for all the great replies !! Certainly got a few people thinking it seems. I will post some photos after Easter of the brakes mounted on my H145 diff along with the 13" wheels fitting over. Will still go with the vanette assy for the racecar but search for a 4.11 centre for circuit work and keep the 4.6 for hillclimbs. Thanks for the 200B master cyl. tip as I will be using the series 1 B/B fronts so they match. Will modify Bluebird struts to have 1200 spring platform and sleeve bluebird bottom balljoint to accept 1200 balljoint and arm. (just for the exercise and to retain my current reinforced lower arms). Will most likely manufacture adjustable coil platforms at a later date. Have a new set of JTS flares but they seem designed more for offside of car than nearside. Is this the case ? I can't just turn them over for nearside as they may fit but just don't look as good. Any tips greatly appreciated !! Cheers and THANKS again to all !!!

i dont want to put a vanette diff in the coupe...its heavier and I think overkill for a 130hp A15. BUT a way to go might be to put a Bluebird H165 disc brake rear in the coupe. Do you know what the measurement is of the Bluebird rear is over the ute rear? ....as I really need to improve the rear track. The rear disc setup from the bluey is the way to go with a 200B Master cylinder. I will also be using brake bias as well.
Any info on slotting solid discs?
i think some Willwood racing discs are solid and slotted...anyone wont to confirm?

y u put a nother dif in the datsun

oh yeah

make sure that the 1200ute axle forge flashing clear your new backing plates, it can be a drama if you have to pull off the nice new wheel bearing you've just pressed on

Converted, if you go to the wreckers and buy Bluebird rear discs, disc backing plates, and callipers they will bolt onto a 1200 ute (H165) diff. The other thing you will need are the bolts that hold the backing plates to the housing, the bluebird ones are longer.

Be careful when removing the backing plates from the Bluebird axles. DO NOT under any circumstances press against the Bluebird backing plate, they are alloy and you will destroy them.

The only other drama you might have is the hand brake levers clearing the rear springs. Keep in mind that the Bluebirds had their hand brake inside the rear disc.

Use a 200B master cylinder and 200B/Stanza front callipers. I didn't remove the pressure retaining valve from the rear on the one I did, but this was an application thing, I wanted to make sure there was no rear brake knock off, but that's a different story.

Have fun

According to my parts book, the H190 diff in the 4 speed wagon came with a 3.89 to 1 ratio. [35/9]
This might be quite good for cruising, but may not be the hot setup for hillclimbing.

The front calipers from the late 200B [810] [Girlock] use the same pads & repair kit as the series 1 Bluebird only the caliper mounting lugs were diferent. If you use the serirs 1 rear disc brake setup, then modified 200B struts with these brakes will mean that the brakes match front & rear. The 200B master cylinder has the same specs as the series 1 master cylinder, even though it looks completely diferent. The booster is much smaller on the 200B & this may mean that it is a better proposition to adapt to a 1200. The pressure bias, front to rear, on the 200B & the series 1 Bluebird is 450lbs, while the series 2 Bluebird has a 550lb bias.

Daniel Blues:- Are we able to have this priceless thread placed in the tech section??
Now can I confirm that if I go to the wrecker and get a rear disk setup off a Bluebird with a H165, then I will be able to put that on my coupe with a H165 on it. Also, will the braking system be balanced with 200B alooy girlocks and the solid disk up front? What master cylinder should I use for a dual system setup required for IPRA?
One more question, can I "slot or groove" a solid disk without damaging it or weakening it?

OK guys

Bluebird S 1, 2 & 3, Vanette, 1200, 1200ute, 120Y (H145 not borg warner), Stanza, can't think of anymore off hand, oh yeah sunny, all use the same rear wheel bearing, what this means is the backing plates are interchangable.

H190, the nose is the same length as the H165, I know this because when I went from a H165 to a H190 in my old Rally car I didn't need to change the tail shaft.

G'day b310Gx,
i am in the Camden area and we have met briefly at oran park. The h190 I have came from pick & pay @ Blacktown (from a A15 vanette) but they do have a couple of 2.0 litre (?) ones as well. Nothing for the datto lover at Ingleburn yard but it's soooo clean and under cover ! Thanx for the tip on the ute tailshaft !! my bluebird diff is the H165 so axles match - sweeeet. Will still measure up on the H145 to test the disc rear end possibility as well.
Haven't pulled the centre out of the H190, but by turning the axle through 1 revolution 1 got about 4.6 so it's a screamer !! See you at the trck someday, Cheers
